▎ 摘　　要

NOVELTY - Self-limiting temperature graphene heating membrane assembly comprises a battery pack (11) and a heating membrane assembly (12) for heating the battery pack, where the heating mold assembly includes a heating film (121), a positive electrode wire (122) and a negative electrode wire (123). The heating film includes a peripheral heating film (1211) and multiple transversely or longitudinally arranged interval heating films (1212). The peripheral heating film is wrapped around the outer periphery of the battery pack, and the interval heating film is interspersed between multiple cells of the battery pack transversely or longitudinally. USE - Self-limiting temperature graphene heating membrane assembly for power batteries. ADVANTAGE - The self-limiting temperature graphene heating membrane assembly avoids abnormal heating of the power battery, and has uniform heating, lightness, low cost, and safe use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for prepring a self-limiting temperature graphene heating membrane assembly for power batteries, which involves combining polyethylene glycol, solvent, conductive filler, adding additives to the grinding and dispersing integrated machine according to the proportion and stirring, and then grinding to the fineness below 10 microns with a three-axis roller press, stirring water-based resin and solvent according to the ratio until the resin is dissolved, then add the above-mentioned organic functional materials, adding the water-based defoamer, continue to stir and adding pH regulator to adjust the pH to 8-9, adding an appropriate amount of thickener to the above mixture to adjust the viscosity to 20000cps, printing water-based self-limiting temperature heating ink on the substrate by using the corona-treated PET as the substrate, and the printing thickness is 12 microns, using printed conductive silver paste on both sides of the printed substrate, and then compositing the copper foil strip through a polyester film with glue into a heating film and riveting the positive and negative electrodes Copper foil on both sides. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of self-limiting temperature graphene heating membrane assembly.
